In creative, breaking the extended part of a piston/sticky piston, will drop an item.
The piston shouldn't drop a piston in creative.
I broke an extended piston and it dropped a piston.
1. Place a piston.
2. Put a lever or something down.
3. Power the piston.
4. Break the extended part of the piston.
